Saget brings his raunchy humor to the Wilbur Theatre for two shows on Jan. 15 — one at 7 p.m. and one at 9:45 p.m. (And trust us, it is raunchy. We caught a performance by Saget years ago in Saratoga Springs that was definitely rated R.) These days, you can hear Saget narrating "How I Met Your Mother" or catch him on A&E's "Strange Days with Bob Saget."
